The 1976 All-Ireland Junior Hurling Championship was the 55th staging of the All-Ireland Junior Championship since its establishment by the Gaelic Athletic Association in 1912. Derry began the competition as defending champions, having defeated Louth in the 1975 final. Louth defeated Mayo in the 1976 final to claim the county's first All-Ireland Junior Hurling Championship title.
Format
Connacht was the only province to stage a junior hurling championship in 1976, which was won by Leitrim. This was a standalone competition which had no bearing on the All-Ireland series. Instead, the winners of the respective 'A' and 'B' sections of the 1976 National Hurling League Division 3 would go forward to contest the All-Ireland final.
Louth secured a place in the final by beating Derry in the Division 3B play-off. Mayo topped Division 3A to automatically qualify for the decider.
All-Ireland final
Louth led by eleven points at half-time (4-06 to 1-04) and stretched their lead to fourteen early in the second period. Despite a Mayo resurgence, they held on to win by a five-point margin.
